@Milheiro Zstd level is compression level right? That I’m aware of. Makes sense if you increase compression that it would take longer to capture/deploy. What I was experiencing was linux kernel level errors, only when deploying to a virtual disk that resides on the xenserver’s local storage array. I wonder if it is something like Truenas where it performs worse when you let the storage controller handle the array vs a soft-raid controlled by the OS.
